Madonna exposing her own breast in public is basically just another Tuesday. After all, she's been doing it since the 80s.
But when the material girl pulled down the top of an unsuspecting fan in the middle of a concert, well, that was a little unusual.
During a show in Brisbane, Australia, Madge brought an audience member on stage and began to gush over her.
"She's the kind of girl you just want to slap on the ass... and pull..." she said before yanking down the woman's top and revealing her bare breast to a sold-out stadium of concert-goers.
Luckily, the fan seemed to take it in stride and even gave Madonna a little side hug after re-adjusting her top.
"Oh my god, I am so sorry, sexual harassment!" exclaimed the singer in a mock attempt at an apology.
"You can do the same to me if you like," she added.
Unfortunately (or fortunately?), the fan declined the invitation.
This is just one in a series of recent disturbing events for Madonna, who is reportedly in angst over a custody battle with ex Guy Ritchie for their son Rocco.
A source close to the singer said that Madonna has been boozing and popping anti-anxiety meds, which has led to her bizarre behavior.
At a concert earlier this week in Brisbane, witnesses say she showed up two hours late then chugged from a bottle of tequila and crawled around onstage like an animal.
During the same show, she grabbed a flask from an audience member and downed whatever was in it.
